Definitions

  • the present invention relates to an image reading device and method.
  • the present invention relates to an image input device that illuminates a transparent original image, photoelectrically converts the image light sensed by a one-dimensional CCD into image signals, converts the image signals into digital signals after executing various processes on the image signals, and outputs digital signals on a (personal) computer and output equipment.
  • such film regardless of whether the film is unexposed or already developed, is stored in a film cartridge 51 as continuous film.
  • Perforations 53 are provided along the top edge of the film 52.
  • An exposure section 55, etc., is provided in the central section of the film 52.
  • a magnetic recording section 54 is provided along the bottom edge of the film 52.
  • An aperture unit 51a and a spool 51b are formed in the film cartridge 51.
  • Japanese Unexamined Patent Publication Hei 5-75922 proposes a video monitor retrieval unit to read the film image within the film cartridge 51 with a two-dimensional CCD sensor.
  • the image reading system is capable of outputting an image obtained by prescanning on a computer monitor.
  • images are read into a personal computer or the like using the above-described technology, it is impossible to see more than one frame at a time of the images, and only the magnetic recording information from one frame at a time can be viewed. Consequently, when a user wants to look up a plurality of information items, it is necessary to operate the device as many times as are frames in the spool of film, which is troublesome. Consequently, this is inconvenient when the aim is to compare a plurality of images and information because it is impossible to see the information on the magnetic recording medium simultaneously when there are a plurality of images.
  • the video monitor retrieval unit disclosed by Japanese Unexamined Patent Publication Hei 5-75922 only outputs film images as video signals.
  • the image is displayed on the monitor (CRT) one frame at a time.
  • the retrieval unit displays one frame at a time on the entire monitor screen. Therefore, if the operator of the camera desires to see a certain frame after verifying all twelve frames on the monitor, the operator has to remember the number of the desired frame from among the twelve frames.
  • the video monitor disclosed in Japanese Unexamined Patent Publication Hei 5-75922 uses a two-dimensional CCD sensor.
  • Two-dimensional CCD sensors with a large number of pixels are expensive, and the distance between the photoelectric conversion elements which comprise the two-dimensional CCD sensor is uneven due to problems in construction and the like.
  • the sensors with a small number of pixels are relatively inexpensive, but they are only capable of reading originals coarsely, resulting in a deterioration of image quality (such as low resolution). Hence, inexpensive but highly precise reading of film images is urgently needed.
  • An object of the present invention is to provide a device that can handle information from a plurality of images recorded on a magnetic recording layer.
  • Another object of the present invention is to provide an image input device capable of reading film with a magnetic recording layer using a one-dimensional CCD sensor.
  • Yet another object of the present invention is to provide an image reading system capable of displaying images of a plurality of frames on a monitor, thus enabling the operator to verify the desired frame in the case when the shooting images of a plurality of frames are in the film cartridge 51.
  • a method for processing a plurality of frames of a film each frame having an image section and a magnetic section.
  • the method comprises prescanning at least one of the image sections and the magnetic sections of the film, and simultaneously displaying a thumbnail display of said plurality of frames on a monitor.
  • an apparatus for processing a plurality of frames of a film each frame having an image section and a magnetic section
  • the apparatus comprising structure for prescanning at least one of the image sections and the magnetic sections of the film, and structure for simultaneously displaying a thumbnail display of the plurality of frames on a monitor.

  • a floppy disk drive, an optomagnetic disc drive or the like may also be used for recording device 44.
  • a floppy disk drive and an optomagnetic disc drive record information on recording media such as floppy disks or optomagnetic discs.
  • Cartridge loading chamber 1a of scanner 100 is adapted to receive a cartridge 51 of film 52 having a magnetic recording layer, as disclosed in Japanese Unexamined Patent Publication Hei 5-75922.
  • Fig. 2 will be used to describe film 52 having a magnetic recording layer.
  • Film 52 can be housed inside film cartridge 51, on one end of which is attached spool 51a. On the film 52, a single perforation 53 and a magnetic recording part 54 are provided for each photo frame.
  • a "0" frame region which cannot be photographed onto, is provided prior to the first photo frame.
  • perforation 53a and magnetic recording part 54a are provided.
  • information indicating whether film 52 has been developed and information indicating the type of film are displayed by an optically readable label.
  • the information indicating the type of film includes information as to whether the film is negative or positive, information about whether the film is color or black and white film, and information indicating the film manufacturer and model number.

  • Illumination member 10a is a device used to illuminate film 52.
  • Illumination drive circuit 10 is controlled by a microcomputer 2 in order to drive illumination member 10a.
  • Light emitted from illumination member 10a is reflected by mirror 8, collected by lens 9 and reaches linear image sensor 21, as indicated by optical axis 15.
  • Linear image sensor 21 is a unit used to convert film images into electrical image signals.
  • Image signal processing circuit 22 is used to digitize the image signal that is read. In addition, when the image signal received is a signal from a negative film, image signal processing circuit 22 converts the signal into a positive image signal.
  • Frame memory 3 is used to record image signals output from image signal processing circuit 22.
  • the lens 9 is a variable power focus lens or a fixed focus lens. If the lens 9 is a variable power focus lens, the reading range of the film 52 is magnified or reduced by variable power orders from the computer 40. If the lens 9 is a fixed focus lens, magnification and reduction are executed by processing the image data within the computer 40.
  • the illumination unit 10a can have three different colors of light source and can form image signals of red, green and blue (RGB) by irradiating each of the RGB colors.
  • the second method is to provide filters with RGB colors between the illumination unit 10a and a one-dimensional CCD sensor 21 and to form RGB image signals by changing the color filters.

  • the rewinding-side spool 16 is shaped such that the tip of the film is wound easily, and a convex hook (not shown) that engages the perforation 53 is formed on the spool axis.
  • the microcomputer 2 can be implemented as a single special purpose integrated circuit (e.g., ASIC) having a main or central processor section for overall, system-level control, and separate sections dedicated to performing various different specific computations, functions and other processes under control of the central processor section. It will be appreciated by those skilled in the art that the microcomputer 2 can also be implemented using a plurality of separate dedicated or programmable integrated or other electronic circuits or devices (e.g., hardwired electronic or logic circuits such as discrete element circuits, or programmable logic devices such as PLDs, PLAs, PALs or the like).

  • Computer 40 performs a warning display on monitor 41 in accordance with the warning received. It would also be acceptable to provide a display device on scanner 100 and to perform the warning on the display device. By determining whether a developed film cartridge is loaded, it is possible to prevent undeveloped film from being extracted from cartridge 51 erroneously.
  • step S301 When the determination in step S301 is YES, the microcomputer moves to step S303.

  • step S2422 settings for the accumulation time of RGB for shading correction and color correction at each frame, and settings of the amount of illuminating light and the like are conducted on the basis of the image information that has been coarsely read. Furthermore, the photographer, after verifying the thumbnail displays and magnetic recording information on monitor 41, can indicate the frame numbers for which scanning is desired using keyboard 42, can indicate the reading precision, and can further indicate the reading range. Scanning is started after these condition settings have been completed.
  • the picture image reading device of the present invention is a device that reads images on film having a magnetic recording section, the film being wound and stored inside a cartridge. Furthermore, the device comprises prescanning and scanning means (S2402-S2406, S2410-S2413 and S2415-S2418 (Fig. 24)); conveyor means (12-13, 18-20) that conveys the film; conveyor control means 2 that controls the conveyor means during prescanning so that the film is conveyed at a constant speed; retrieval means 25 that retrieves the information stored in the magnetic recording section when the film is conveyed at a constant speed by the conveyor control means; and photoelectric conversion means 21 that reads the image information and converts such into electrical signals when the film is conveyed at a constant speed by the conveyor means.
  • prescanning and scanning means S2402-S2406, S2410-S2413 and S2415-S2418 (Fig. 24)
  • conveyor means (12-13, 18-20) that conveys the film
  • conveyor control means 2 controls the conveyor means during prescanning so
  • the picture image reading device that uses a one-dimensional photoelectric conversion means (CCD line sensor) reads image information precisely during a scanning operation, a single line of film is conveyed and image signals are obtained for R (red), G (green) and B (blue).
  • CCD line sensor CCD line sensor
  • the magnetic recording information is read while the film is conveyed at a fast speed in a first direction and the image information is read while the film is conveyed at a slow speed in a second direction, it is possible to reduce the time needed for prescanning and it is also possible to obtain a highly precise image because the speed is slower during reading of the image information.
